“Yeah, why not?” would be my answer to this question.
Apparently, it’s a question being asked more and more lately in some states. I wouldn’t mind seeing a federal republic with twice or even three times as many states as we have now.
Conceptually, this would be no different from secession within the EU or any other federal or confederal arrangement.
Can anybody answer my answer (which is actually a question)? That is to say: what are some objections you can think of to more decentralization of power within the US?
